U.S. exports of Check Valves (SITC 74730) totaled $61.4M in August 2026.
Importers of Check Valves paid $7.5M in duties in August 2026, an average duty rate of 15.54% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataDesigned to permit flow in only one direction and prevent backflow automatically, check valves serve as passive safety devices in pipelines, pumping systems, compressors, and chemical-process equipment. SITC 74830 — wait, SITC 74730 — covers swing, lift, ball, and wafer-style check valves across a wide range of materials and pressure classes. Trade professionals should note that check valves sourced from certain origins may carry Section 301 or antidumping exposure, and that body material and nominal pipe size typically govern subheading selection at the HTS level.

At the SITC level, all check valves fall under 74730 regardless of internal mechanism. At the HTS 10-digit level, classification typically turns on body material (e.g., iron, steel, brass, plastic) and sometimes on pressure rating or end-connection type rather than on the specific check mechanism.
A manufacturer's technical datasheet showing body material, pressure-temperature rating, and end-connection standard (ANSI, DIN, JIS) is the most useful supporting document. Country-of-origin certification is also essential given the potential for trade-remedy applicability on certain sources.
